ı think they re first teacher for us but they re no best for me ... ı learnt alot of thing from books- school- friends- social events-internet... but ı agree with CSMaster that they re the most effective teachers for us .....

A teacher is not necessarily a person, who teaches you text books only. Each stage of life has its own teachers. There was a stage, where our parents taught us something concrete. Who taught us how to walk? Who taught us how to speak? There are many things like that, for which parents are best teachers for sure. You can compare teachers, because they teach us relative knowledge. But parents teach us concrete and practical knowledge. So they are the best teachers, at least, for some stage of our lives.

I think they are the most effective teachers, but not the best.

Hi... At the beginning of your life perhaps but after that probably not the best...

yes, i think so they teach us their experience and all things to be wiser of the life and they are the most person who care about us and our future.
